Enclosure 1

Safety Evaluation of Generic Letter 83-28, Item 2.1 l Vootle, Units 1 and 2 Introduction Generic Letter 83-28 was issued by the staff on July 8,1983. It describes i intermediate-term actions to be taken by licensees and applicants to address  ;

the generic issue raised by the two anticipated transients without scram that l occurred at Unit 1 of Salem Nuclear Power Plant. l This report is an evaluation of the response submitted by Georgia Power Company, the licensee for the Vogtle Electric Generating Plant, to Item 2.1 I of Generic Letter 83-28. I Item 2.1 requires the licensee to confirm that all reactor trip system (RTS) l components are identified, classified, and treated as safety-related and that '

an effective vendor interface program is established for these components as indicated in the following statement:

Licensees and applicants shall confirm that all components whose functioning is required to trip the reactor are identified as safety- i related on documents, procedures, and information handling systems l used in the plant to control safety-related activities, including maintenance, work orders, and parts replacement. In addition, for these components, licensees and applicants shall establish, implement l and maintain a continuing program to ensure that tie vendor information 1 is complete, current and controlled throughout the life of the plant, and appropriately referenced or incorporated in plant instructions l and procedures. '

E_ valuation The licensee responded to the requirements of Item 2.1 by letters dated November 8, 1983, and May 20, 1985. The May 20 submittal was in response to the staff's request for additional information dated March 18, 1985.

In the initial submittal, the licensee committed to meeting the staff position regarding equipment classification and the vendor interface program. In the latter submittal, the applicant stated that the RTS components are indicated as safety-related in the Vogtle Final Safety Analysis Report and had been identified as safety-related on the applicable electrical diagrams and in the equipment index, that maintenance activities and work orders involving safety-related components were designated as such on 3ssociated documents, and that procedural controls were established to ensure f. hat maintenance and procurement activities associated with safety-related components would be treated as safety-related activities.

For the vendor interface program, the licensee stated that a Vogtle operating experience program had established controls to ensure that Westinghouse (nuclear steam supply system (NSSS)) technical bulletins used to communicate technical information and recommendations are reviewed and controlled for the life of the plant, and that these controls provide provisions to ensure positive feedback to Westinghouse.

Conclusion Based on our review of these responses, the staff finds'that the licensee's statements confirm that a program exists for identifying, classifying, and treating components that are required for performance of the. reactor trip.

function as safety related. Further, a program exists to ensure that Westinghouse (NSSS) technical bulletins are reviewed and controlled for the life of the plant, and that these controls contain provisions-to ensure positive feedback to Westinghouse. This program meets the requirements of Item 2.1 of Generic Letter 83-28, and is therefore acceptable. Therefore, Item 2.1 is resolved for both Units 1 and 2.
